That bowl is about 3 times the diameter and weight of a normal Egyptian style bowl and it's very shallow although the perspective of the photo doesn't show it. I know it's a tombac bowl since I saw it being used by the owner of the cafe in Tunis for that purpose. At the time he didn't have anything else for the application so he sold me what he was using. It also came with a wire mesh to hold more leaf but since I never have the time to smoke for more then an hour or so I never used it. The bowl you showed looks more like a Saudi style tombac bowl but like a said the designs very quite a lot depending upon where you go.
Thanks for the complement on my Syrians. I am a big fan of of them as well the Iranian stuff I have. I love the style but heft of the construction is even better.
